Wow. Excellent write up. Very well detailed and documented.

I was thinking about doing one of these that were more graphic than the written ones, but I'm glad you were able to do it. Too bad I have the bad habit of pulling the engine and doing this.

Absolutely amazing! Very nice write-up.. one of the best I've seen. Thanks for taking the time out to put all this together. I'm sure a lot of people will put this to good use.

A big +1 for you!

one thing that some of the older model L and brightons owners need to keep in mind, is that there are a few steps in there that are not the same. the main on i could see being the slave we don't have a wet clutch system. and there are only four bolts on the engine.

another thing to add, is that the support H brakcet doesn't need to come off unless you really really want to take it off. also helps to leave it on when sliding the trans out from under the car. also, if your exhaust system is all rusted and you don't want to risk breaking them, you can just undo the entire system and lay it on the ground, there's about 4 hangars, the one bolt on the trans and the header to engine bolts.

Very well done DIY, thanks!

Depending on what other maintenance/repairs I'm doing determines if I pull the engine or the tranny for a clutch change, but this will definitely get used next time I pull the trans.

Thanks for taking the time to make a comprehensive write up. Great pics and good suggestions.
One thing you may want to mention is when you're sliding the transmission back on to be sure the small metal shield on the bottom of the engine is slightly bent down so it doesn't prevent them from sliding together. This happened when a friend and I were putting mine back together. We were so puzzled because you can't really see that shield with the engine crossmember in the way. After pushing it down a little they just fell into eachother.

I will be using this Friday for sure, as I have a new clutch coming Tuesday, and a vacation day planned. This should be a HUGE help.

Thanks again!

VERY VERY good write up. The level of detail in your explanation is spot on.

I will say though, I'll probably never go this route. Removing the engine seems "easier" to me, but I guess that's just a preference...

Again, excellent write up. I'm sure it will serve plenty of people well on here.
